Self landing,
saffer's technique works brilliantly with Tribals.
Using lifeline- while holding life line disconnect from bar so you don't drag bar up with you, hold both life line and centre line so you keep a little tension on the front lines as well. This keeps kite on ground as you walk up lines to kite.

no signs of wear as you describe.

with setup laying lines down wind keeps all lines in perspective.
disconnect lifeline at junction of two yellows. setup is axactly like any 5thline kite. The Y 5th bridle is just a bit longer. when you wind up the lifeline Y into a roll use the velcro of the dump valve to secure it for packing, this stops it getting tangled when packing.
